TO-252-3L
SN79xxx
3 Terminal 1A Negative Voltage Regulator
Description
The SN79xxx series are three-terminal Negative regulators providing
over 1A output current with internal current limiting, thermal
shutdown and safe area protection. These regulators are useful in
a wide range of applications. Although they are just fixed voltage
regulators, the SN79xxx series can be used with external components to
obtain adjustable voltages and Currents.
Application
Consumer and personal electronics
SMPS post-regulator / dc-to-dc modules
High-efficiency linear power supplies
TO-220F-3L
